Locally Adaptive Passive Error Concealment
for Wavelet Coded Images

Joost Rombaut, Aleksandra Piˇzurica, Member, IEEE, and Wilfried Philips, Member, IEEE



Abstract—

This letter presents a novel locally adaptive error concealment
method for subband coded images. For each lost low-frequency
coefficient, we estimate the optimal interpolation weights
from its neighborhood. The calculation of the interpolation weights
is optimized in the mean squared error sense, and it takes into acco ....etc

Turbo TCM Coded OFDM Systems for Non-Gaussian Channels



I. INTRODUCTION
Orthogonal Frequency Division Multiplexing (OFDM)
modulation has been a promising solution for efficiently
capturing multipath energy in highly dispersive UWB channels
and delivering high data rate transmission. The main
idea behind OFDM is to split the transmitted data sequence
into N parallel sequences of symbols. The transmission is
carried out in parallel on different frequenci ....etc

VISION BASED PROCESSING FOR REAL TIME 3-D DATA ACQUISITION BASED CODE STRUCTURED LIGHT-IMAGE PROCESSING

Abstract: The structured light vision system is a successfully used for the measurement of 3D surface in vision. There is some limitation in the above scheme, that is tens of picture are captured to recover a 3D sense. This paper presents an idea for real-time Acquisition of 3-D surface data by a specially coded vision system. To achieve 3-D measurement for a dynamic scene, the data acquisition must be performed with only a single image. ....etc

Turned-off electric home appliances generally they still require standby power when they are plugged in. In this paper we present a way to reduce the standby power of a socket. Our socket supplies the appliances with power when the user turns them on. When the user turns them off, our socket shuts the electric power off and reduces the standby power to zero. Our design uses an MCU which receives signals from a PIR sensor which detects the user when approaching the socket and the appliances. A power detector provides an MCU to control the SSR On ....etc

One fundamental property underlines most biological databanks; their availability in text format Report gives an approach to retrieve and convert biological data stored in textual flat files into information in formats more suitable for further analysis and use by client applications. Extracted data can be exported into different data structures (CORBA objects, DBMS, C structures, HTML reports). These data structures are loader objects. They are generated based on loader specifications, which specify how to get specific pieces of information an ....etc

MAP EQUALIZATION AND DECODING IN WIRELESS MOBILE CODED OFDM
OBJECTIVE
 OFDM suffers extra performance degradation in multi path channels due to ICI
 Bit error rate(BER) increases with this ICI
 To reduce the BER suitable equalizer is needed.
 That equalizer should not limit the advantages of OFDM
OFDM
